When asked to think about an alien spaceship, the first thing that comes to mind is undoubtedly a flying saucer. This image goes back to Jordan Peele’s new movie Nope (“No”). But how does this fit with reality?
According to astronomer Colin Stewart, attempts have already been made to create ships that resemble flying saucers. Thus, the VZ-9 Avrocar was created in the 1950s.
According to the documents, the engineers tried to achieve vertical landing and vertical take-off of the ship using jet engines located along the edge of the disk. Also, experts believed that their device as a whole could reach speeds of up to Mach 3-4 (about 4-5 thousand km / h), climb to an altitude of 30.5 km and have a maximum flight range of about 1900 km. . But in reality, experts could not lift the ship more than a few meters, and its speed was no more than 56 km / h. The central jet engine made the ship noisy and exposed the pilot to high temperatures.
Then, in 2008, information appeared about a small UAV resembling a circle. This device will be able to coat the ship with electrodes that can ionize the air to create plasma. Also, due to the magnetic field, the plasma will accelerate and as a result lift will occur. According to Stewart, this is the most likely way to launch a flying saucer-like device.
If we talk about whether aliens have already entered the Earth’s atmosphere and whether they can, the astronomer is skeptical. Stewart believes that aliens will most likely not be the same size as a human. This is due to the fact that their planet will still be different from Earth. That is, if gravity is stronger on their planet than ours, then they will be lower than humans, and if it is weaker, then they will be higher.
But even if aliens have created flying saucers, the chances of such travel are still slim. To move from one star system to another, two systems are needed: the real flying saucer and a cruiser or rocket that will get this saucer to the solar system.
